"Smart factory" is a recent buzzword that refers to the increased utilization of IoT technology at production sites.This trend increases the importance of network environments especially wireless network, to connect everything.A diverse range of things must be connected to a production site network, from production facilities, various sensors, and cameras, to people working on site.However, their locations are not necessarily fixed.The use of wireless networks to efficiently connect these things to the network is increasing.However, production sites need to change line arrangements in accordance with the products being manufactured, which disturbs the onsite radio environment, necessitating a redesign of the network configuration.The wide variety of connected devices, including sensors and production facilities use different wireless technologies, including Wi-Fi, Bluetooth, and Bluetooth Low Energy (BLE).This situation is likely to cause signal interferences.Fujitsu offers technology to solve these challenges for customers and help them with the installation of wireless networks at their factories.This paper describes Fujitsu's wireless solution that ensures reliable wireless connections even at production sites with complex configurations.It also introduces its technology for visualizing a radio environment as a vital element for the installation, operation, and maintenance of the network, and its technology for designing the optimal wireless device configuration.
